Topic-Specific Sentiment Analysis Can Help Identify Political Ideology

Ideological leanings of an individual can often be gauged by the sentiment one expresses about different issues. We propose a simple framework that represents a political ideology as a distribution of sentiment polarities towards a set of topics. This representation can then be used to detect ideological leanings of documents (speeches, news articles, etc.) based on the sentiments expressed towards different topics. Experiments performed using a widely used dataset show the promise of our proposed approach that achieves comparable performance to other methods despite being much simpler and more interpretable.Comment: Presented at EMNLP Workshop on Computational Approaches to Subjectivity, Sentiment & Social Media Analysis, 201

Experiments and Analysis of Aqueous Electrode Processing for Energy Storage

There is an ever-growing demand for Lithium-Ion Batteries in a widespread series of applications, where battery life and reliability are of key importance. There exist novel materials that are helping increase battery reliability and life but there is a lack of environment friendly and cost-effective processing techniques that are used to produce such energy storage devices. Current processing techniques use N-methyl-2 pyrrolidone as a solvent for electrode slurry, which is expensive and has the potential to damage the environment, increasing the risk of cancer and reproductive toxicity. Therefore, there is a need to move towards a solvent that is environmentally friendly, cheap to produce and can serve as a potential replacement. In this work, the use of deionized water has been experimentally evaluated to create an electrode processing technique that could become an environmentally friendly and cost-effective technique to produce Lithium-Ion Batteries. This study focuses on the concepts of Lithium-Ion Batteries and their current electrode processing techniques. The proposed Aqueous Processing technique for electrode manufacture is discussed in detail along with a discussion of challenges currently being faced in this area. A 1-D physics based drying model is also developed as part of this study that is based upon evaporation, diffusion and sedimentation. My analysis has shown that the proposed Aqueous Processing can be implemented using low-cost preparation methods and deionized water. Drying temperature has an effect on the agglomeration of particles that could impact the electrochemical performance of the electrode. My analysis has also shown that an optimal amount of dispersant needs to be added to reduce the effect of agglomeration while maintaining good film adhesion. The results from the 1-D show that at a higher drying temperature a larger volume fraction is observed at the top surface of the electrode

Characterization of CYP2D protein from human brain cerebellum

To date, knowledge in characterization of CYP proteins has been limited to immunoblotting, RT-PCR, immunohistochemistry and so forth; therefore, it is the intention of this study to investigate: (1) What kind of CYP2D protein is present in brain with modern proteomic tools; (2) Whether, CYP2D6 in brain is same as the liver CYP2D6; and (3) If CYP2D7 is present, can CYP2D6 polymorphism be found in the brain?;To answer these questions, this study used a one-step method of isolation of protein by immunoprecipitation followed by its identification using 2D-blots, nanospray LCMS, immunoblots and immunohistochemistry. Probing of immunoprecipitated proteins with polyclonal CYP2D6 antibody revealed two major CYP2D6 immunoreactive bands. Similar banding pattern resulted from matched human liver microsomes suggesting there are more than one CYP2D isoform(s) exist in these tissues

A comparative study of supraglottic airway devices Baska mask and ProSeal-laryngeal mask airway in short gynaecological procedures

Background: Baska Mask® (BM) a newer Supraglottic Airway Device (SAD) considered to cause low incidence of Postoperative Pharyngolaryngeal Complications (POPC). This study was designed to assess efficacy, safety and early and late POPC between BM and commonly use ProSeal LMA (PMLA).Methods: Patients between 18 to 60 years of age undergoing elective short gynecological procedures were randomized into two groups, to receive ventilation with either BM (group 1, n=50) or an PMLA (group 2, n=50).Results: There was no significant difference in the ease of insertion for both the devices (p<0.24). There was no significant difference in the number of attempts for both the devices (p<0.69). When compared to PLMA, the time (in seconds) required for insertion of BM was significantly less in duration (20.9 vs. 16) (p<0.0001). Between the two groups significant hemodynamic changes noticed after removal of SGA. The blood staining of device was similar in both groups. Failure to place device, postoperative complication like laryngospasm and bronchospasm did not occur in both BM and PLMA groups.Conclusions: In conclusion, findings of this study support that BM takes significantly shorter placement time and provides a better seal as compared to PLMA but without any reduction in laryngopharyngeal complications

Constraint On The Cosmological Constant From Gravitational Lenses In An Evolutionary Model Of Galaxies

We study the effect of the cosmological constant on the statistical properties of gravitational lenses in flat cosmologies (Omega_{0}+lambda_{0} = 1). It is shown that some of the lens observables are strongly affected by the cosmological constant, especially in a low--density universe, and its existence might be inferred by a statistical study of the lenses. In particular, the optical depth of the lens distribution may be used best for this purpose without depending much on the lens model. We calculate the optical depth (probabilty of a beam encountering with a lens event) for a source in a new picture of galaxy evolution based on number evolution in addition to pure luminosity evolution. It seems that present day galaxies result from the merging of a large number of building blocks. We have tried to put limit on the cosmological constant in this new picture of galaxy evolution. This evolutionary model of galaxies permits larger value of cosmological constant.Comment: Latex file with two figures, 24 page
